This invention relates to adjustableslicing machines and is particularly adapted for slicing circular ice cream bars. 1

An object of the invention is to provide a slicing machine of the characterreferred Y to, the length, of the slices of which may be regulated to any determined sizewith. ease and dispatch. I

Further objects of: the invention are to provide a slicing machine of the character referred to that is very pleasing in appearance, strong, compact and durable, relatively light in construction, very sanitary, very simple in its method of assembly, and comparatively inexpensive to manufacture and operate.

With the foregoing and other objects in View, the invention consists of a novel construction, combination and arrangement of parts as will be hereinafter more specifically 2 described and illustrated in the accompanying drawings, wherein is disclosed an embodiment of the invention, but it is to be understood that changes, variations and modifica tions may be resorted to without departing from the spirit of the invention as claimed.

Figure 8 is a fragmentary detailed section taken substantially online 88 of'Figure 1. Referring to the drawings in detail, 10 indicates the base of the slicer which is'relatively rectangular in'configuration and having a flat bottom. The upper face of the base 10 is flat for one-half its width, as indicated at" 11. ,The base 10 is further formed with an upstanding rib 12 adjacent one side thereof. The upstanding rib 12 is above the level of the fiat portion 11 of the base, and

between the upstanding rib and the flat face on the flat face of the base 10. A circular f spindle 17 has the opposite ends thereof supported in openings 18 in the supporting plates 15,116, and the spindle 17 is prevented from turning by a set screw 19 threaded through an opening 20 in the support 16, the inner end of which merges with the opening 18. I 7

-The inner end of theset screw 19 is pointed and is sufficiently hard to bight into the spindle 17 so as to obtain a firm grip thereonoto prevent the turning of the spindle. The spindle 17 extends longitudinally of the base 10, in spaced relation to the upper flat face 11.

- An upstanding supporting brace 21 is secured totheside edges of the base 10 adjacent the fiat face 1 11 and projecting inwardly therefrom are a pairrof longitudinally spaced cars 22, 23, that servev to strip the ice cream or other articles being sliced from theknife blade to be presently described, 7

The knife is indicated generally at 24Cand ,is formed' with ahandle 25 at one end and an elongated sleeve 26 at the other end projecting laterally from the handle and intermediate the sleeve and the handle the knife is formed with an arcuate blade receiving shank 27 One side face of the shank 27 is recessed .at 28 and intermediate the ends of the recess thereis an outset lug 29. Seated in the recess is the knifeblade 30 having a slot 31 therein .that fits aboutthe'lug 29 to provide additional support to prevent the blade from slipping. V

The blade is further secured in the recessed shank by a pair of screws 32. The free edge of the blade is curved and bevelled as at 33 to provide a knife edge for cutting articles such as ice cream or the like. The knife 24 is ro tatably mounted on the spindle 17 by having the sleeve 26 circumposed thereabout. The handle 25 and the blade 30 are disposed between the ears 22, 23 and the bevelled edge 33 is in alineinent with the groove 14 in the depression 13.

The sleeve 26 disposed on the spindle 27 projects toward the support 15 and has disposed thereabout a tensioned coil spring 34, one end of which terminates in a prong 35 that is anchored in an opening in a ring collar 36 rigidly secured to the spindle 17 by a set screw 37. The oppositeend of the coil spring 34 is formedwith a U-shaped hook'35 that overlaps the shank of the knife 24 adjacent the sleeve 26.

Keyed to the spindle 17 is a collar 36 thatabuts the base of the shank of the knife adj acent the sleeve 26 so as to prevent the spring 34 from moving the knife out of alinement with the groove 14. The spring 34 eX- erts a twisting pressure upon the knife 24 so that the handle will normally be urged to a vertical position and the knife edge 33 free of the groove 14.

Beginning at the side margins, the upper face of the support 16 is provided with a plurality of transverselyspaced U-shaped pockets 37 and detachably secured over the upper face of the support is a cover plate 38 secured to the support by means of screws 39. The cover plate closes the upper ends of the pockets 37 and extending through the cover plate, one in communication with each pocket are a plurality of threaded openings 40. In each of the openings there is threadably supported screws 41 the inner ends of which extend into the pockets 37.

A relatively elongated U-shapeu guide yoke indicated generally at 42 projects inwardly from the end support 16 in spaced relation above the spindle17. The legs of the yoke 43, 44 are square in cross section and are seated in the end pockets of the series of pockets 37. The end screws of the series 41 rigidly couple the ends of the legs of the yoke 42 in the pockets. A plurality of gauge fingers 45 are slidable in the other pockets 37 of the series and selectively adjustable in rigid relation to the support 16 by means of the screws 41.

The gauge fingers 45 are square in cross section and may be of unequal lengthas the purpose requires. 'The fingers 45 are disposed in the same horizontal plane asthe legs of the yoke 43, 44. The gauge fingers are transversely spaced from each other and lie within the yoke 42, the inner ends of which may be adjusted as desired.

An arcuate abutment plate 46 projects laterally from, and is secured to a portion of the peripheral face of a sleeve 47 that is slidable longitudinally on the spindle 17. The inner end of the abutment plate 46 is formed with an apertured neck 48 that is rotatable on a reduced portion 49 of the sleeve. The neck is maintained in vertical position by a washer 50 in loose abutment therewith and the washer 50 is rigidly anchored to the reduced portion 49 of the sleeve by means of a pin 51.

From the foregoing it will be seen that the abutment plate 48 is rotatable on the reduced portion 49 of the sleeve. Anchored to the sleeve 47. and projecting radially therefrom is the shank 52 formed on its outer end with a ball handle 53. Theshank 52 is confined within the yoke 42 and is adapted to rest on eitheroneof the legs 43, 44thereof, when the abutment plate is in certain positions. In the application of the invention, the length of the slice of the article is determined beforehand. The number of gauge fingers 45 will .determine the numberof different sized slices'that'can be cut by the slicer. In the form of the invention shown, there are four sized slices that may: be cut .by a simple manipulation of the abutment handle 53. The length of the slice. of course, will be determined by the distance the abutment plate may be disposed from groove 14.

Furthermore, it is to be noticed that the stepped relation of the inner ends of the gauge fingers 25 may be set as desired. The first cut may be maintained by holding the sliank52lagainst the bight portion of the yoke and since the arcuateblade fits snugly down into the bottomof'the depression 13, the length of the slice will be between the groove 14 and the plate46... The second length of slice is obtained by holding the shankin abutment withthe inner end of the first finger of the series 45. j

The third length slice is obtained by holding the shank in abutment with the inner end of the second-of the seriesof gauge fingers 45. Likewise, the fourth length slice Will be obtained'by holdingthe shank 52 against the inner end of the third of the series of gauge fingers 45. V

t is to be noticed in the present invention, that with the exception of the;support most of the parts may be disassembled and cleaned and furthermore, it is to-be noticedthat all of the parts are very easily assembled and furthermore could .be' manufactured in great quantities and assembled with great economy.

It is to be understood,thatsbyfdescribin g in detail herein any form, structure, or arrange- -1nent, it isinot intended to limit the invention beyond the terms of the several claims, or the requirements of the prior art.
